INHTATION MOSAIC ENAMEL.

SPECIFICATION forming part of Letters Patent No. 631,490, dated August 22, 1899.

Application filed December 29,1897. Serial N- 664,4.l.0. (Specimens.)

vented Substitutes for Mosaic-Enameled Ar` ticles and a New Process for the Manufacture Thereof, (for which I have obtained Letters Patent in France for fifteen years, dated June Ilo 2l, 1895, No. 248,330,) of which the following is a full, clear, and exact description.

My invention has for its objectthe manufacture of substitutes for ordinary enameled articles 'known as Mosaic enamels, and

v particularly cloisonn enamels. In such enameled articles enamel is commonly applied either in the recesses formed at the surface of the article or in the holes or perforations cut into the said article.

The object of my invention is to provide Ineans for obtaining cheap substitutes for the said enameled articles, and my process consists, essentially, in the application of gelatin and coloring-matters, as will be more fully described hereinafter.

According to myinvention I take an openwork article or frame made of metal, wood, pasteboard, or any other material, so as to produce a base for the formation of cloisonne- Work of suitable design, and I apply thereto' a colorless and transparent coating of gelatin, which closes the apertures therein. This coating of gelatin may be deposited on the article in superposed films, preferably by dipping the said'article into a solution of gelatin, and in order to impart to said coating a suitable thickness it is convenient to dip the article many times in the solution, allowing the film to dry after each immersion. When a suitable coating of gelatin has been obtained on the article, coloring-matters are applied to the back of the said gelatinous film in the apertures and the appearance of enamel is so imparted to the colored parts of the article. In the case where thin articles are to be treated the gelatin can be applied exactly in the same way-as for depositing a-thin sheet or ilm of gelatin -upon paper. In such case the solution of gelatin is placed on a glass plate, upon which the article is then laid. After drying the film of gelatin strongly adheres to the article,.which can then easily be detached from the'glass plate. The gelatin used may be colored; but it is preferably colorless, so as to allow the article provided with the film of gelatin to keep its usual apof the gelatin coat filling the.

brooches, buttons, vases, small boxes or y chests, ornaments of all kinds, Snc.

When the substitutes for mosaic enamels are to remain transparent, no other opaque material is mixed with the coloring-matters. Articles like lamp-globes, lanternglasses, vases, &c., can then be obtained.

In the accompanying drawings I have shown enlarged views of an ornament embodying/my invention.

In the drawings, Figure l is a face View of the ornament; Fig. 2, a sectional view, on a greatly-exaggerated scale, of the said ornament, the section being taken, let us say, on line 2 2 of Fig. 1.

In the drawings, a is the open-work base or support for the gelatinous matter. or coating of gelatinous matter, c the colori ing-matter, and d the plastic backing.

What I claim, and desire to secure by Letters Patent, is f 1. The herein-described process for the production of imitation mosaic enamels, especially imitation cloisonn-work, which consists in applying to an open-work body or frame a coating or film of gelatinous matter, said coating or lm closing the apertures in the reticulated body and applying a coloring substance at the rear of the said films formed in the apertures, whereby the color will be visible through the gelatinous matter in the apertures and the finished structure will pre sent the appearance of a mosaic enamel substantially as and for the purposes set forth.

2. As a new and useful article of manufaca ture, the herein-described imitation mosaic IOO enamels, consisting of a base comprising` an open-Work body or frame having its interstices closed by films of gelatinous matter backed with a colored substance, whereby the gelatnous matter in the iuterstices will present the appearance of colored enamel, bordered by the surrounding framework of the body, substantially as described.

The foregoing specification of my new process for the manu facture of substitutes for mofo Salio-enameled articles signed by me this 11th day of December, 1897.
